MANDEL MANDEL AND LOUIS M ANDEL, OF CHICAGO, ILLINOIS.

CAMERA,

To all whom it may concern Be it known that we, MANDE MANDEL and LOUIS MAXDEL, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certainnew and useful, Improvements in Cameras, of which the following is a specification.

This invention relates vto cameras, and

moreparticularlyto those of a class which whichaccess may be had, also closed to the light, at any and all times, as by the hand of the operator, to place the sensitized members in exposure position one at a time, and to remove them therefrom and to place them in a fluid receptacle 'from whichthey may be removed one or more at atime without affectin the remainder of the sensitized members within the compartment of the camera.

Another object of the invention is to provide an improved device of this class which is simple in construction and effective and eflicient in operation.

For the attainment of these ends andthe accomplishment of other new and useful objects, as ,will appear, the invention consists in the features of novelty in the construction, combination and arrangement of the several parts generally shown in theaccompanying drawings and described in the specification, but more particularly pointed outin the appended claims.

In the drawings Figure 1 is a'sectional view in elevation of a camera of this class constructed in accordance with the principles of our invention; Fig. 2 is a plan view of such camera taken on the line 22 of Fig. 1; Fig. 3 is a view in elevation of a centering lens or finder disposed on to the camera; Fig. 4 is a sectional view 0 the same showing the construction whereby the position of an a-pertured member of the finder may be changed Fig. 5 is a view in elevation taken on the line 5-5 of 'Fig. 2,

Specification of Letters Patent.

and in such" production to make them of.

cards of different sizes without necessitating the use ofa dark room, orwithout re-load ing the camera in such a dark room at each time an exposure is made. The novelty resides in the combination and the features set forth in the claims hereto appended. In the specific construction disclosed the camera box is formed with separate compartments, one or both of which are closed to the light,

and to one of which compartments access may be had by the hand of an operator, whereby he is enabled to select and place in exposure positiona number of sensitized members of different sizes, and to"remove them from such exposure position and to place them in a suitable solution or bathv light; Another feature of importance is the means by which the exposed members may be recovered from the fixing bath without admitting light to the interior of the camera compartment.

Referring now more particularly to the drawings, a camera box 11 is provided with Patented Feb. 8, 1916. Application filed April 12, 1912. Serial No. 690,260.

a lid or cover 12, which is securedthereto by hinges 13 or other suitable means, and

held in place bylatches 14, This box may.

tubular connections 17 to effect the operation of the lens.- Any other operating mechanism may be provided, inasmuch as the A'threaded member the bottom thereof, which is. adapted to secure the camera to a tripod or other suit able supporting device, and at the top of of novelty of the present invention does not reside in this feature. .18 is secured to the box 11, preferably in erably disposed directly. over the lens in the end of the box. This finder com prises a'casing member (see Figs. 3 and 4) which contains a lens 21, and a rotatable partition 22, which is provided with an aperture 23 substantially preferably oblong or rectangular in form. The casing is also provided with a slotted portion 24, through 'tition and adapted to cover the opening is an exposure device. This exposure device comprises a number of supports, one hinged upon the other, and the whole rotatably mounted on the partition. The preferred construction of this exposure device as shown in the accompanying drawings comprises a plate 37 preferably circular in form, which is retained in connection with the partition by means of a flang'ed'member 38 in which the plate member 37 is rotatable. The re taining rim or flanged member 38 is preferably provided with projecting lugs 39, and the plate with a detent 40 to engage the lugs which an car 25 formed integral with the 39, whereby the rotative movement of the partition 22 extends, and by means of which plate 37 is limited in both directions of rothe partition may be rotated in any desired tation. Preferably these limiting stops are or suitable position, the limiting positions substantially 90 degrees, or one-quarter of a being preferably as-shown by the'full and revolution apart, so that the'plate may be dotted positions in Fig. 4. At the rear end presented with one axis horizontal or vertiof the camera and in line with the finder 20 "cal as desired. This plate 37 is provided is a peep sight 26, by means of whichsight with an exposure aperture or opening 41, and th'efinder'the camera is directed toward which ispreferably longer in one direction the object which it is desired to photograph.

At the rear of the camera'and secured thereto in any desired orsuitable manner to an opening in the box of the camera is a sleeve 27, composed of fabric or any other suitable material impervious to light. This sleeve and the opening in the box of the camera is of a size to permit the hand of the operator of the camera to be inserted through the sleeve and within the interior of the camera through the opening in the end of the box, the sleeve at this time forming "a passage way closed to the light, so that access may be had to the interior of the camera at any time without exposing the interior of the camera to the light. This sleeve may be secured in position in any suitable manner, such, for example, as by meansof the clamping ring 28, which is fixed to the box by any suitable fastening devices. The interior of the camera is provided with holders 29 and 30 preferably formed by bending strips of metal or other suitable material and securing them to the sides of the camera box. These holders are adapted to contain the sensitized members31 and 32, which are preferably of different sizes, and

another holder 33, may be positioned in the plate or support 42 is also provided with an camera and adapted to contain sensitized members 34 of any different size or kind ably fixed in position is a partition 35, which substantially divides the interior thereof into separate compartments, one pf which contains the said holders and to WlllCh access may be had from without'through the sleeve '27, and the other of which may be designated as the exposure compartment, and in the end of which the-exposure lens 15 is disposed.

The partition 35 is provided with an aperture or opening 36, and secured-to the parthan another, so that an exposure may be made with the longer axis of the opening in a horizontal or vertical position. Pivotally connected to the plate 37 is a perforated member or support 42, which is preferably slightly larger in size than the exposure aperture 41 in the plate 37 so that when the support 42 is placed over the opening 41 it will be substantially closed. Secured to the plate 37 and disposed about the opening 41 around the edge of the pivoted support 42 nected to or formed integral with the support 42. These cars 46 and 47 are preferably formed with a slight bend, so that when 1 they are brought into engagement the pivoted support 42 is removably locked in en gagement with the plate 37. The pivoted opening 48, and pivotally mounted thereon is a second support 49 provided with a perforation or opening 50. This plate 42 is provided with upright flange 51, having-the engaging lugs 52 and 53 similarto the lugs 45 and 46, respectively, of the flange 43, the lugs 52 being adapted to limit the outward movement of the support 49, as previously described, and the support 49 being provided with lugs 54 to engage with the lugs 53 and to hold the support in position. Another function of the flanges 43 and 51 is to position the sensitized pieces or members to be exposed through the lens so that they will be centered in the exposure apertures, thereby excludingthe light from the storage com partment and preventing the unexposed members contained therein from being exposed to the light when a sensitized piece is placed in exposure position. These pivoted supports 42 and 49 are, preferably provided at the top edge with bent clips or ears 55 and 56, by means of which the pivoted supports may be readily separated from the member to which they are pivoted and thereby to facilitate the positioning of a sensitized piece in the exposure position.

In the preferred construction theexposure apertures in the plates or supports are preferably rectangular in shape, so that exposures may be made with the greater dimension in either a horizontal or a vertical position. In thepreferred construction and "as illustrated in the present exemplification of the invention, it is contemplated that the last pivoted support as the support 49 be provided with an opening 50, which is circular in form, the rear of the support being provided with a grooved retaining flange 57, which is adapted to receive and to hold round members in connection-with the support 49 in exposure position in the opening 50. This opening is for the purpose of exposing round sensitized pieces, such as buttons and the like, and the flange is preferably formed of magnetized metal, so that a metal button, or a button composed of or provided with metal capable of being attracted thereby, may be held in position over this exposure opening 50.

The edges of the exposure a ertures may be provided with any desire fanciful or decorative design, which will of course appear upon the edge of the exposed member. In the present exemplification of the invention this is exemplified by the perforations 58.

V The bottom of the camera adjacent the rear thereof is provided with an opening or slot 59 through which exposed members may be discharged from the camera into a developing bath. It is necessary that this bath be contained in a suitable receptacle, which is closed to the light and which prevents light from being admitted throughthe opening 59 to the interior of the camera. A flange plate 60 is therefore provided which is secured to the end of the camera box, and which extends outwardly from the end thereof substantially half of the width of the plate 60. This plate is provided with an aperture 61 which registers with the opening 59 in the bottom of the camera box,

and with an opening 62 which is disposed in the extending portion of the plate and which latter is provided with a hinged lid 63. The flanged portion 64 extends downwardlv and a receptacle 65 is positioned beneath the plate 60, and within the flanges 64. The receptacle 65 is composed of any desired or suitable material, and ig preferably provided with two compartments oppositely disposed, so that one of them registers with the opening in the bottom of the camera, while the other one registers with the opening 62 in the extending portion of the plate 60. This receptacle is rotatable in the plate 60, and is preferably secured, in position by means of a threaded member 66 provided with a thumbscrew 67, the threaded member extending through the receptacle from the bottom thereof and being threaded into the flange plate 60 substanstantially at the center thereof, so that the flanged portion 64 may extend around the upper portion of the receptacle 65 as closely as possible to exclude lightfrom the receptacle, and from the interior of the camera. To facilitate the removal of exposed members from within the .compart ments of the receptacle, they are provided with lifters 68 of any desired or suitable material, which are preferably provided with perforations 69 (see Fig. 2) to permit the bath or solution to drain more rapidly from the articles or members as they are removed from the compartments.

It is evident that in order toremove an exposed member from within the camera it is necessary .to drop it through the opening 59 into registering compartment ofthe receptacle 65 and then to rotate the receptacle until this compartment registers with the opening 62 in the extending portion of the plate 60, whereupon the device 68 may be withdrawn carryin with it the exposed article. It is also evi ent that by having a number of separate compartments in the receptacle the baths contained therein may be of difl'erent strength for different purposes. In the present exemplification of the invention the receptacle 65 is provided with stops 70 to limit the movement of the receptacle in either direction, so that the compartments may be brought more readily into registering position with {She opening in the bottom of the camera In operation it is necessary, of course, to fill the holders 29, 30 and 33 with the sensitized members. Thismay be done in a dark room or the coverings of packages containing the sensitized material may be removed through the sleeve impervious to light and the camera is then ready for operation. The

' lens is of course closed and a sensitized piece device and placed 'in the receptacle 65 through the opening 59 and the bottom of the camera box. From the receptacle it may be removed as previously explained and in the Well known manner. v llt is to be understood, of course, that the said operations are performed by the operator by the sense of touch alone, for it is manifestly impossible for him to see the interior of the camera, but with very little practice it is possible .for him to acquire the necessary knowledge to carry out these operations by the sense of touch alone, and without actually seeing the operations carried out. It will also be evi dent that it is possible to" replenish the storage compartment Without employing a dark room, by inserting packages of sensitized walls of one compartment, means impervious material'through the sleeve and removing .the coverings therefrom after the packages are within the camera. It is also evident that pictures of various sizes maybe made one at a time, and that these pictures may be made wit-hthe long axis horizontal or "vertical, by reason of the fact that the en- 25 tire exposure device is rotatable in the partition. v

The sighting or finding device in the top of the camera makes it possible to shift the camera accurately in the proper directlon,

and to position it with respect to the exposure to be made. By means of the adj ustable front lens or finder the subject may be accurately centered upon the exposed member. 1 V
